As illustrated to advantage Fig- To aZZw/wmitmay conccmc. 4 Be it known that I, HAROL GLAUDE HAR- Pnn, a citizenof the United States, and. a resident of Detroit, in the county of llayne and State of Michigan, have invented cer tain new and useful Improvements in VVindow Guards, of which the following is a specification. i 1

My invention relates to devices adapted ure 3, the lugs L are constructed from single lengths ofinetal bent to formthe lips 17 which are arranged in spaced relation to a base 18,; with the, latterprovided with screw receiv ng openings. H

The frame F carries at its lower. edge hinges H, one leaf 19 of which is formed integral with the frame whilethe leaf20 is hingedly. connected to the firstwleaf and formed with screw-receiving openings.

In the applied position of the window" guard as shown in Figures 1, 2 and 8, the twolugs L are secured to the vertical pertions of the lower window sash S and in such manner that the lipsl? occupy reverse positions. ,By means of the hinges ll. the frame F is hingedly supported upon the sill ofthe window casing K. screws 6X5 tending through the openings of the leaves 1 20 and secured within the window sill so that the frame canoccupy an inactive position as shown" injdash lines in Figure 2 or an active position as shown in solid lines in thesame figure. In the inactive position of the frame, it'occupies a vertical positionat the inner side of the window casing, the leaves 19 and 20 permitting of the frame occupying this inactive position.

In the active position of the frame, it lies parallel and contiguous to the lower sash the lugs maintaining the frame ll'ltlllS "position by so adjusting the sash S so as to permit of the lips 17 being passed from the outer side of the frame through the recesse s 16 to the inner side of the frame so that the frame is confined between the lips and the window sashin the manner clearly shown in Figure 3. The construction of the lugs L is such as to allow ofunre stricted sliding movement of the sash S with respect to the frame while at the same time maintaining the lips in embracing position to the frame so that the latter is main tained in active position irrespective of the position of the sash.

By this arrangement. it will be seen that guarding the window when in open position against persons or obJeots entering or falling therethrough, a purpose of my m this character which is of extremely simple and inexpensive construction and which in applied position in a window is capable of occupying, an inactive and active position in which it successfully spans an open window for the purpose described.

I will describe oneform of window guard embodying my invention and will then claims. 1

In the accompanying drawings:

Figure 1 is a view showing in front elevation a window-and window casing having applied thereto one form of window guard embodying my invention.

Figures 2 and 8 are vertical and trans verse sectional views taken on the lines 2- -2 and 3-8,respectively,of Figure 1.

Figure 4 is a fragmentary detail perspective view of a portion of the guard frame and one of thehinges.

Similar reference characters refer to si1nilar parts in each of the several views.

Referring specifically to the drawings and particularly to Figures 1 and 2, I have here shown a conventional form of window casing designated at K in which are mounted for vertical sliding movement two window sashes designated at S and S. i

The window guard forming the subject matter of my invention comprises in the present instance a frame designated generand is made up of longitudinally extending bars 15 and transversely extending bars 16 which connect the first bars at regular spaced intervals throughout their length. The frame F is formed of any suitable metal or other material with the bars 15 and 16 preferably formed integral with each other so that the frame as a whole could be stamped or moldedwith one opera S can be moved to any vertical position, and that when raised, the frame will serve to guard the opening formed thus preventlng the passage of objects through the open winwith the frame in active position, the sash to prevent the passage 01 smaller objects .therethrou F'Jhen it is desired todisconti'n'ue the use 071': the guard. it can be swung to inactive post ion by moving the sash S so that the lips lTwil-l register with the recesses 16- thus permitting the lips to disengage the frame so thatfthe latter can he swung downwardly to inactive position.

The outermost bars 16 are provided at points above therecesses 16 with openings 21 designed :r'or the purpose of receiving oversize hooks (not shown) which are adapted to be secured to the window sash in the event one desires to permane itly secure the wii'idow guard to the window.
